To all whom it may con cum:

Be it known that I, GEORGE W. IVALK, of Pittsburg, in the .county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Machines for Cleaning and Greasing Pans; and Ihereby declare that the following is a full, clear. and exact.description thereof, reference being had to the accompanying draw-'ings, which form partof this specification. I

This invention is a novel machine for cleaning and greasing .pans, beingespecially designed for'use in bakeries where a large number of pans areused.

The machine in brief comprises a number of pairs of rotary brushes whichare preferablyarranged on a vertically disposed axis so that the panscan be held upside down thereover and cleaned or greased with facility;all the brushes in a row may be driven by a common belt; the brushstandards are adjustable so that the brushes in each pair can be set atany desired distance apart so as to enable the brushes to operate m0stadvantageously upon the pans; the

' ries for greasing the pans; the cleaning and greasing devices beingsubstantially alike exceptthat longer bristles are used on the greasingbrushes. The brushes are not intended to entirely fill the pans; anumber of pairs ofsuch brushes are preferably arranged in each machine,and the pairs are. adjustable to or from each other so that a number ofpans may be simultaneously cleaned. It is customary in many bakeries tohave a number of pans connected by straps so that they can be handled asunits; and by my machine such sets of pans can be cleanedsimultaneously, as one pan, and may I be greased in a similar manner.

I will now describe the invention in detail as embodied in the machineillustrated in the accompanying drawings, in which- Figure 1 is a sideview of the complete machines Fig. 2 is a plan view. Fig. 3 is anenlarged end view thereof, with near drive shaft and pulleys removed.Fig. 4 is an enlarged detail horizontal sectional view on line 4-4, ofFig. 1. Fig. 5 is a detail perspective view of one of the brushes andits supporting brackets.

1 represents a base or table upon which the operative parts aremounted;'upon this table are adjustably mounted a number of brackets 2,each of which isprovided wit-h bearings 2 for preferably verticallydisposed brush spindles 3 upon which are mounted brushes 4. ,Eachbracket 2 is adjustably secured to table 1.by means of a bolt and nuts 2transfixing a slot 2 in the base of the bracket and a slot 1 in the topof the table. The brackets 2 are arranged in pairs, so as to havebrushes 4 in pairs; the pairs of brackets are preferably disposedtransversely of the table as shown, and the brackets in each pair can bereadily adjusted to .or from each other by reason of the slots 2, andcan be adjusted longitudinally of the table by reason of the slots 1";the construction being such that the brushes'4 can be adjusted anywherefrom the minimum to the maximum distance apart, and thus be arrangedtooperate most effectively upon pans of any diameter. As shown there arefour pairs of cleaning brushes 4 mounted in this manner in one series onthe ma- .chine; and.there are.four pairs of greasing brushes 4 similarlymounted in-one series on the machine; the series of greasingbrusheslying parallel with the series of cleaning brushes- The brushspindles 3 are provided with spools or pulleys 3, and the pulleys 3 'ineach longitudinal row of brush-spindles are driven by a common belt orrope 5 which extends from a pulley'6 on a driven shaft 6, at one end ofthe machine, to and around the several pulleys 3 and to and over anidl'er pulley 7 on an idler shaft 7 at the other end of the machine, andthen straight back to the pulley 6 ,the belt being given one turn aroundeach pulley 3 so that all the brushes will be driven in unison and atthe same speed by a common belt. The other rows of brush-pulleys may besimilarly driven by belts 5 from pulleys 6 on shaft 6 as shown. This isa very simple and efiicient form of drive, and enables the brushes'to beindep'endently adjusted without necessitating changing, of the belts,and insures uniformity of rotation of the brushes.

The brushes 4 are preferably cylindric and may be removably fastened tothe upperends of thespindles 3 by screwing them In using the device theoperator takes a pan and turns it upside down over a pair of the brushesas indicated in Figs. 13; and then moves the pan around over the brusheswith a gyratory motion until it is cleaned; for ordinary sized pans twobrushes are employed, this facilitates the cleaning operation, and asthe brushes are small they can clean the corners more thoroughly thanlarge brushes. For very small pans one brush can be used.

In large bakeries it is customary to connect several pans together, byriveting them to straps, so that such pans can be handled as one; and mymachine is particularly adapted for use with such sets of pans, as thepairs of brushes can be adjusted so that all the pans in a set can besimultaneously cleaned as indicated in Figs. 1-8. The

vertical arrangement of the brushes and adjustability of the brackets,whereby it is possible to adjust the brushes in each pair, and also toadjust the pairs of brushes,'renders the machine very useful andadaptable for cleaning all sizes of pans and sets of pans. The greasingof the pans can be effected in the same manner as the cleaning; theworkman after cleaning the pans simply placing them upon the greasingbrushes in the same way.

Having described my invention What I claim as new and desire to secureby Letters Patent thereon is:

1. In combination a table, adjacent relatively adjustable bracketsmounted on the table, a vertically disposed brush spindle journaled ineach bracket, a brush on each spindle, said brushes being parallel andhaving their axes vertical, and means for driving the said spindles,

2. In combination a table, pairs ,of brackets adjustably mounted on thetable, vertically disposed brush spindles journaled in said brackets,brushes on said spindles, and pulleys on the brush spindles; with adriven shaft at one end of the table, an idler shaft at the other endthereof, belts running from pulleys on the driving shaft successivelyaround the belt pulleys on a row of v spindles to and over pulleys onthe idler shaft and back to the driving shaft.

In testimony that I claim the foregoing as my own, I aflix my signaturein presence of two witnesses. I
